Re: AW: st: AW: Flexible end of numlist

Obviously it doesn't. I didn't read that part of Michael's post
carefully, and so my suggestion was simply aimed at making the end of
his numlist flexible ... apologies to Michael for any confusion it
might have caused.

The help advises against this use of the -foreach- loop structure.
See -h

foreach-:" If you wish to loop over many equally spaced values, do
not
code...", instead use -forvalues-. Apart from that, you can have
Stata

evaluate an -expression- as the endpoint of a -numlist-, in this
particular
case half the -local- "r":
*************
local r 10
forv i=1/`=`r'/2'{
di in red `i'
}
*************

Betreff: st: Flexible end of numlist
Dear stata listers,
I need to program a loop and want to use the "foreach i of numlist
1/10"
begin. However I want to have the end of numlist not to be fixed,
but more
flexible. To be more precise, the end of the numlist should be half
the
number of the variables involved in that loop. Does anyone have an
idea how
to do that?
The variables which are involved in that loop are for instance
pat_se1
pat_se2 pat_se3 pat_se4 and contain the month (pat_se[odd]) and the
years
(pat_se[even]) of a specific business starting activity. I have
here a
first draft of that loop
foreach i of numlist 1/2 {
local j=`i'*2
local k=`j'-1
local t=round(`i'/2)
gen PATENTS_SH`i' = ym(pat_se`j', pat_se`k')
format PATENTS_SH`i' %tmn_CY
if mod(`i',2)==0 {
lab var PATENTS_SH`i' "Patenting, end `t'. spell, real time"
}
else lab var PATENTS_SH`i' "Patenting, start `t'. spell, real time"
}
Thanks for your help
Michael
